Description
Technical field
Invention is related to seamless steel pipe manufacturing field, and in particular to a kind of multi-functional seamless punch.
Background technology
Hot-puncturing process is most important process in seamless steel tube production, is the first procedure of flow of metal.Hot-puncturing process
Effect of the machine in seamless steel tube production unit is into hollow hollow billet by solid blank pierced billet.Perforation procedure is by piercer roll
Rotation, the mandril anti-thrust trolley that two section of outlet platform drive top, push rod to run to working position, and in the position by mandril anti-thrust
Dolly locks, and the pipe heated pushes away base hydraulic cylinder by import desk and pipe is pushed into punch main engine bed, and pipe bites, perforated,
After rolling, the blocking device that two sections of outlet platform is opened, and mandril anti-thrust trolley runs to rear position, by taking off pipe device by hollow billet
Separated with top.Because in perforation procedure, top temperature raises, so it is cold to be usually mounted with a top after de- pipe device
But water tank, a steel pipe is often worn, top is cooled down using the intermittent time.
In addition, seamless steel pipe is in process of production, after blank heating, eleven punch 11 is entered by push rod.Due to mandrel ends
Top contacted for a long time with the blank of high temperature, continuous production can cause top to deform, and reduce the service life of top, simultaneously
Also the surface quality of seamless steel pipe internal wall is have impact on, perforation failure is resulted even in when serious, causes blank to scrap.Typically
Situation, after push rod is retracted, have spray equipment and spraying cooling is carried out to top, but if the seamless steel pipe diameter produced
Very big, top diameter is also relatively large used in production, causes the cooling effect from outside spray bad.Therefore, on the market
Have and be similar to patent name《Tappet of seamless steel pipe puncher cooling device》, the top of Patent No. 201310029626.0 is cold
But device, cooling water is passed through top inside, so can effectively cool down top, but this divides in the technical scheme of patent, its
Water recovery apparatus is located at push rod side wall, causes the cooling water of backflow to be reused after can not effectively collecting；Moreover, this cooling structure
If applied on the push rod with rotating function of prewhirling, the cooling water of backflow then can when in use, due to centrifuge from work
With getting rid of to surrounding, the production of surrounding is influenceed.
With the progress of puncturing technique, hollow billet length now requires sufficiently long top up to more than 10 meters after perforation
One section of bar and outlet platform, two sections match therewith.According to the device (such as accompanying drawing 1) of prior art, i.e.,：Cooling water tank II and de-
Pipe device I occupies two stations respectively.After push rod is elongated, not only its rigidity can be deteriorated, and rolling center is easily deviateed in top during perforation
Line, hollow billet wall unevenness is caused, and one section of outlet platform, two sections of lengthenings can be made, floor space is big.
In addition, during seamless steel pipe is produced, the steel billet heated is sent to punch pass by blank pushing machine
In, pipe advances under roll effect, along roll line direction in rotation, realizes and once bites, when pipe is with coming directly towards phase
After contact, pipe be still to drive top and push rod continue to rotate and advance together, realize it is secondary bite, in the case, for
For less top and push rod, above-mentioned action can be still realized, but for larger top and push rod, due to weight
Increase, realize that above-mentioned action is relatively difficult, often roll card accident, influence Rolling production.For this problem, mesh
Before, tube rolling production in, also take some measures, as useful friction pulley drive push rod rotation, its shortcoming be often because
Frictional force deficiency, and push rod can not be driven to rotate；Also have to use and a set of dress for driving push rod to rotate is installed on push rod dolly
Put, but can so make the weight penalty of push rod dolly again；More also it is to use wobble gear mechanism, its shortcoming is to be often
Make gear engagement relatively good, it is necessary to increase gear width.
In summary, for the shortcomings of the prior art, it is necessary to provide a kind of multi-functional with novelty
The device of property, practicality and creativeness.
The content of the invention
It is an object of the invention to provide a kind of multi-functional seamless punch, so as to solve the problems, such as to mention in the prior art

Sealing is fixed；The connector A7 and connector B8 are extended through provided with through hole A14 and through hole B15, the cooling water pipe 4 it is outer
Footpath is respectively smaller than through hole A14 and through hole B15 diameter；The end connection that the cooling water pipe 4 is located at cooling bath 10 is provided with spray
Mouth 5.
The present invention is passed through the backflow cooling water for cooling of plug set by ring flange by being provided with cooling of plug structure
Apopore connected with the small in-car return pipe of push rod, be easy to collection and the recycling of recirculation water；And returned cold will not be caused
But water is thrown away, and ensures the production environment in place.
With reference to shown in Fig. 5, Fig. 6, Fig. 7 and Fig. 8, an alternative embodiment of the invention is provided with de- pipe device, is to cool down
The front panel design of water tank 31 is de- pipe die support, takes off pipe die 35 and is arranged on water tank front panel, is fixed by briquetting 33.De- pipe
Mould is the equipment for separating hollow billet with top 2, push rod after perforation, and its main function is to block the head of hollow billet 310 to make
Hollow billet positions, it is allowed to comes directly towards, push rod is extracted out by die orifice.Top is put into water tank after die orifice extraction, and water tank is built with water spray
Pipe 32, sparge pipe are connected by flange 38 with workshop feed pipe, and sparge pipe is by two Semicircular water pipe groups for carrying nozzle 35
Into in the intermittent time of perforation, from four circumferential top water sprays, realizing the cooling of top.Waste water after cooling of plug is by installing
Sluice is discharged into the adjutage 36 of water tank bottom, tank upper cover has cover plate 37.
The course of work of the present apparatus is：After perforation, mandril anti-thrust trolley is with push rod, top 2 from hollow billet 310
Extract, run to de- pipe device, de- pipe die 35, which blocks hollow billet head, positions hollow billet, it is allowed to comes directly towards, push rod passes through die orifice
Extract out.Top is put into cooling water tank 31 after die orifice extraction, and sparge pipe 32 realizes top from four circumferential top water sprays in water tank
Head cooling.
The present invention compared with prior art, is integrated due to cooling water tank and de- pipe die being designed, when de- pipe die is by hollow billet
